The engine component drive system and the accessory drive systems(engine accessory drive gearbox and power takeoff drive) shall be capable ofsimultaneous, operation of all the drives when each drive is subjected
4、 to themaximum permissible torque or power rating specified for the individual drive.c. All drive splines shall be either positively lubricated by engine oil,or incorporate provisions for accessory manufacturer supplied or enginemanufacturer supplied non-metallic shaft-couplings as described in MS14

When the engine manufacturers documentsare used for materials and processes, the documents shall be subject to reviewby the Using Service prior to the start of the PFRT, and unless specificallydisapproved, will be considered released upon arrival of the PFRT and QT. Theuse of non-government
10、 documents shall not constitute waiver of Governmentinspection. The Using Service reserves the right to inspect any and allprocesses of manufacture. The use of magnesium requires specific applicationapproval by the Using Service. Copper and cadmium shall not be used in engineparts which are in direc

The filter housing shallincorporate an automatic shutoff device to prevent oil drainage when thefilter bowl
16、is removed. The filter assembly shall be equipped with adifferential pressure activated pop-out device that will give visual warningof impending bypass, by raising a red indicator, when the differentialpressure across the element exceeds a specified value. Once activated, thered indicator shall rema

Scavenge side filtration may be accomplished by means of strainers orscreens, preferably located at the outlet from each bearing compartment. Eachstrainer or screen shall not impede the flow of scavenge oil and shall alsoprov
